歷年考研真題長難句解析薈萃(16)

1. The existence of the giant clouds was virtually required for the Big Bang, first put forward in the 1920s, to maintain its reign as the dominant explanation of the cosmos.

【譯文】巨大的宇宙云的存在，實際上是使二十年代首創的大爆炸論得以保持其宇宙起源論的主導地位所不可缺少的。

【析句】本句的主干為The existence of the giant clouds was virtually required for the Big Bang，過去分詞短語first put forward in the 1920s在句中作后置定語，修飾前面的the Big Bang。

【講詞】Big Bang是天文學的一個名詞，應該譯成“大爆炸”或“大爆炸理論”。put forward意為“提出”。The Council has put forward valuable concrete proposals on energy conservation.（委員會提出了寶貴而具體的節能意見。）China has put forward three historical sites for UNESCO heritage list.（中國提交三個歷史名勝申請成為聯合國教科文組織的世界遺產。）

UNESCO的全稱是the United Nations Educational,Scientific and Cultural Organization。

2. Astrophysicists working with ground based detectors at the South Pole and balloon borne instruments are closing in on such structures,and may report their findings soon.

【譯文】天體物理學家使用南極陸基探測器及球載儀器，正越來越近地觀測這些云系，也許不久會報告他們的觀測結果。

【析句】本句為連詞and引導的并列分句，主語為Astrophysicists，現在分詞短語（working with ground-based detectors at the South Pole and balloon-borne instruments）是主語的后置定語，兩個并列謂語分別為are closing in on such structures和may report their findings soon。

【講詞】to close in on意為“接近”或“快要”。AOL is closing in on launching video VoIP.（美國在線很快將推出網絡視頻電話。）Deadly bird flu virus is closing in on Europe.（致命的禽流感正在接近歐洲。）

ground based意為“陸基”，即基于陸地，也可以說land based。以類似方式組成的單詞還有web-based（基于網絡的；網上的），如web-based email system（網絡在線電郵系統）。
